Tamas, I recounted some of those mis-attributions in http://dicklyon.com/tech/Hearing/APGF_Lyon_1996.pdf and concluded: Aertsen and Johannesma [AJ80] appear to have coined the catchy name; referring to the envelope, they said: The form m(t) appears both as the integrand in the definition of the Gamma function $\Gamma(g)$ and as the density function of the Gamma distribution, therefore we propose to use ... the term "Gamma-tone" or "$\gamma$-tone." ... The non-hyphenated "gammatone," as an adjective modifying "filter," appears to be due to Patterson et al. [P88].
